Ss watch the video and know they have to finish 6 tasks to join Bai Jingting.To create a scenario to ignite Ss’ interest in this lessonTask 1

To study what can be used to deduce facts1.Brainstorm (2mins)

Ask Ss to observe the inferential usage of modal verbs“ must, can’t, could, might” through some sentences.Ss finish answering the questions and then share their answers.To summarize the inferential functions of“ must, can’t, could, might”2.Choose the right modal verbs. (3mins)

While “could” and might are used to show that people are not sure about something.Finish the modal verbs choosing exercise on their I-pads.To strengthen the inferential usage of modal verbs “must, can’t, could, might”.“Who is best at deducing” Game（2mins）

Based on the pictures given, Ss fill in the blanks and stand up to say out the correct modal verbs as fast as possibleSs look at the picture and sentences, and try to fill in the blanks and stand up to say out the answers loudly.To liven up the learning atmosphere and enhance students’ knowledge about inferential functions of modal verbs “must, can’t, could, might”.Task 2

To study how to use modal verbs in different tenses to make inferences.1.Look and say(3mins)

Let Ss look at the picture and the sentences and try to say out the modal verbs in simple present tense, present progressive tense and present perfect tense to make inferencesStudents look at the picture and the sentences and try to say out the modal verbs in different tenses.To let student come to realize and learn that “must, can’t, could, might” can be used in different tenses to make inferences. 2.Summary and learn(3mins)

(3 mins)

Ask Ss to observe the general question sentences with “can” and different answers, trying to find out the answers to general questions of making inferences.

And then invite one student to come up to share his conclusions.Students observe the general questions and try to find out the rules on the worksheet. Then One student come up to the front to share her idea.

Students observe the general questions and answers and try to find out the rules on the worksheet.

Then One student come up to the front to share his idea.To help Ss summarize how to ask and answer general question sentence with inferential modal verbsPair Work (3 mins)
